Consumer demand is not something that just appears. Demand for oil has largely been induced by decades of urban, housing and transportation planning centered around the automobile. E.G I do not want a car; I don’t like driving and maintaining one is expensive, but I don’t have a viable alternative for many trips I need to make.
Planning according to policies set in large part by auto and oil lobbyists.
You fail to understand the years of marketing, r&d, lobbying and outright anticompetitive practices these companies have been unleashing to "sell more product".
If we had any meaningful regulation, these companies would be forced to begin paying for their products' impacts on climate.
individuals can't absolve themselves of responsibility by blaming the corporations that they buy their petroleum products from.
